>>Charles, I'm typing "LOL" on my Grandpa box keyboard. Which carries a lesson: the QWERTY keyboard's deliberate inefficiency was ripe for replacement from the very start of the digital age, but that layout still dominates- even on the iPad. Just because something is better/newer doesn't mean customers will want it more, which also can be said for certain development tools whose demise was predicted ages ago, and for the Grandpa box itself. ;-)

>It's amazing that QWERTY keyboards have lasted as long as they have. They were specifically designed not for maximize efficiency (most common letters by the strongest fingers, most common runs of letters close to each other) but to reduce it so the mechanical typewriter keys didn't jam. QWERTY is just so ingrained in so many of our muscle memories it will be hard to replace it with a different keyboard layout.

>I am typing this on my laptop At work I have a "natural keyboard," one of those wavy and allegedly ergonomic things. The unnatural keyboard, I have always called them. Splitting my time between the two, at the moment I feel like all thumbs on both of them. My hands are often out of position and I press the wrong letter, CapsLock instead of A, and so on.

What makes the most sense of course is a spherical keyboard - seeing how that's the natural position a person hold's their hands.
Only image I could find of something similar to what I was thinking is this: http://perso.ensad.fr/ari/archives/2005_06/wu/detect2.jpg
I've actually considered attempting to make one myself before as I've never seen one for sale.
